Quick answer: This is the genuine ResMed distal pressure port (part 61121, 1-pack) — an optional attachment for the ResMed Mirage Swift nasal pillow masks. It fits onto the mask's short tube assembly and creates a vent that diffuses exhaled/excess air away from the mask — making therapy quieter, more comfortable, and letting you direct airflow away from a bed partner. One end fits the Mirage Swift short tube; the other connects to standard CPAP tubing. Fits Swift LT, Swift LT for Her, Mirage Swift II, Swift FX, and Swift FX for Her. Note: this is a legacy part — availability may be limited.
What's included
- 1 × ResMed distal pressure port (part 61121, 1-pack)
Mask and tubing not included. Also available as a 10-pack (61124).
About this part
On the Mirage Swift nasal pillow masks, the distal pressure port is an optional in-line attachment that sits between the mask's short tube and your main CPAP tubing. It does a couple of useful things:
- Diffuses excess air away from the mask — it creates a vent point further from your face ("distal" = away from the mask), so the airflow from venting is gentler and quieter near you.
- Redirects airflow — helps steer vented air away from a bed partner, a common comfort complaint.
- Universal tubing fit — one end is shaped to fit the Mirage Swift short tube assembly; the other end connects to standard CPAP tubing from any manufacturer.
It's a small comfort/quietness accessory rather than a sealing or safety part — optional, and ordered separately from the mask.
Compatibility: fits the ResMed Swift LT, Swift LT for Her, Mirage Swift II, Swift FX, and Swift FX for Her nasal pillow masks.
Legacy part: the Mirage Swift family is an older ResMed mask line, and this attachment has been discontinued — it's typically sold while remaining stock lasts. If you rely on one, it may be worth keeping a spare.
